High-voltage sound and light electroscope

The utility model relates to an electroscope, and specifically relates to a high-voltage sound and light electroscope. The high-voltage sound and light electroscope comprises an electricity-testing device and an insulation operating rod. The electricity-testing device comprises a housing, a circuit board which is disposed in the housing and a contact electrode which is connected with an input end of the circuit board and extends out of the front of the housing. The insulation operating rod comprises a telescopic rod sleeve, a fixing rod and a fork head disposed at the top of the fixing rod. Each of two sides of the housing is provided with a positioning ring cooperating with the fork head to realize clamping. Through the structure, the sound and light alarm circuit is added to allow the improved high-voltage electroscope to have a sound and light alarm function; the housing is produced in an integration manner, and electric shock accidents caused by electric leakage are reduced; an free end of the contact ele
